1 Claim. 1

The invention relates to improvements in a mechanical motor.

The object of the invention is to provide a multiple spring motor in which the individual springs are partially rewound, one at a time and in succession, upon every revolution of the driven shaft by the combined power of the remaining springs, whereby the motor will run for a greater length of time.

Another object of the invention is to provide a simple and effective spring motor of this type which can be cheaply manufactured, readily assembled and the individual springs easily replaced.

With the above and other objects and advantages in view the invention consists of the novel details of construction, arrangement and com- 'bination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of an embodiment of the invention partly broken away.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Figure 3 is side elevation looking from the opposite side from that of Figure 1.

Figure 4 is a sectional view on the line 4--4 of Figure 3...

' .Figure 5 is asectional view on the line 5-5 of Figure 2.

Figure 6 is a sectional view on the line 8-8 of Figure 2.

Figure '7 is an enlarged detailed view of the brake construction and Figure 8 is a sectional view on the line 8--8 of Figure 7.

Referring more in detail to the drawings, I8 designates a circular motor frame which may be supported in any desired manner against rotation and has at its center a shaft bearing l2 extending therethrough and in which rotates the shaft Id. The motor frame I8 is provided with twelve cylindrical housings IB in each of which is arranged a coil spring I8 surrounding the tubular drum 28.

Each of the drums 28 has a reduced shaft 22 keyed thereto at 24 and each shaft has formed thereon a ratchet gear 26. The opposite end of the drums 28 receive a reduced shaft 28 which has keyed thereto at 38 the annular flanged collar 32 which receives one end of the spring it the other end of the spring to be connected to the annular flange 34 adjacent the opposite end of the drum 28. The opposite ends of the shafts 28 have formed thereon pinion gears 88 2 which mesh with the ring gear 38. Therefore the gear 36 will be caused to rotate by the spring I8 since the lower end of the spring is held against rotation by means of the flange 34, and the shaft 22 carries the gear 48, the purpose of which will be later explained.

Gears 28 rotate in a housing 42 in the motor frame I8 and spring pressed dogs 44 are mounted in a recess 48 in the housing 42 for engagement with the gears 26. The dogs 44 retain the drum 28 against rotation in one direction by the tension of the spring I8 but the drum may be rotated by hand for winding the spring in the opposite direction as shown in Figure 6.

Mounted in the motor frame I8 and joined integral with the ring gear 38 is a drum 48 which is free to rotate on the shaft bearing I2.

The inner periphery of the drum 48 forms a brake drum adapted to be engaged by the brake lining 58 carried by the brake shoes 52 and 54.

These brake shoes are mounted within the drum 48 and are provided with inwardly extending portions 56 and 58 having openings therethrough in which are mounted the shafts 88 and 62. The shafts are provided with gears 64 which mesh with the gear 86 rotatably mounted in the drum 48 and thus the shafts 88 and 62 are simultaneously rotated. The portions 56 and 58 of the brake shoes 52 and 54 are provided with recesses 68 and 18 in which rotate the cams I2 and 14 carried by the shafts 68 and 82. The end of the shaft 88 is adapted to receive a crank I8 whereby the same is rotated. By this arrangement it will be seen that the shaft 88 is rotated which in turn rotates the gear 66 meshing with the gear 84 on the shaft 82 so that the shafts 88 and 62 are rotated together. The cams carried by the shafts force the brake shoes outwardly for engagement with the drum 48 to prevent rotation thereof and the ring gear 38 formed thereon.

The drum 48 has formed on the lower surface thereof a ring gear I8 of lesser diameter than gear 38 and which drives a pinion gear 88 formed on the bolt shaft 82 mounted in bearing 84 in the motor frame I8. Fixed to the shaft 82 at 8B is the gear 88 which meshes with a gear 98 formed on the upper end of shaft 82 mounted in a second bearing 94 formed on the bearing 84 and the shaft 92 has fixed thereto at 98 on the opposite end thereof a gear 98 which meshes with a gear I88 fixed at id? to a shaft I84 mounted in a bearing I86 formed on the bearing 92.

Thus pinion 88 drives gears 88 and 98 which in 7 3 turn drive gears 98 and I99 and gear I00 meshes with a gear I03 fixed on shaft I4 at I I9.

The shaft I4 has fixed thereto at IIZ a sleeve I I4 carrying an arm II6 provided at its outer end with a segment H8 adapted to engage the gears is carried by the drums 20 on which the springs I8 are mounted as shown in Figures 2 and 3 of the drawings. 7

The motor frame I0 is provided with removable end covers I20 and I22 respectively which are secured to the frame by fasteners I24.

In operation the springs Within the twelve housings are all tightly wound manually the gears 46 providing means for windin the same. In order that access may be had to the gears it for the winding of'the motor the fasteners I2 are removed. The cover I22 being removably connected to the frame by the fasteners I2 may combination of parts may be resorted to provided gear, tubular spring drums within the housings,

a shaft loosely mounted in the upper end of each of "said tubular spring drums, a gear fixed to then be removed so that the gears iii can be 'rotated to wind the springs. I v

'Itjwill be understoodftha't before the springs are Woundthe crank it is rotated so that the brake shoes 522116154 engage the inner periphery of the drum 4'8 of the ring gear 538 and locks the same against rotation. Upon "the release of the brake shoes the spring drums are paused to rotate by the exertion of the springs which in turn rotate'the ring ear 38. "The rotat'ionof the ring gear ttcauses rotation of gear 18 and of its engagement with pinion gear '89 rotates gear trains 38, iii} and 98 "and I93 the engagement of which with gear I08 rotates the shaft It from which necessary ower is derived. The rotation of the shaft I i causes the arm "I It to travel around in a clockwise direction f'and the segmented rack H8 engaging the gearsf' i'u carried by the spring drums so while winding one of the spring drums the springs of the remainingeleven are exerting the power of these springs on the ring gear 38 to cause a rotation thereof which by means of the previously mentioned gears eauses rotating of the shaft I4. Byyoperatin the crank 16' it will be noted-that the speed of the ring gear 33 can be controlledand therefore the speed of. the

drive shaft I4.
